Consisting mainly of a multivibrator, a piezoelectric buzzer chip, an impedance matching unit, a resonator and a shell.
The multivibrator vibrates and emits the audio signal.
Production name: Piezo buzzer, Sound type: Continuous sound, Sound volume: 85 - 95 decibels, Working voltage: DC 3 - 24V.
Impedance Matcher drives the piezoelectric buzzer sound.
Connected to rated power and the buzzer will sound continuously. Can be controlled conveniently.
